of screen Referring to the upper left hand side of the drawings, 1 designates the vertical wall of a building, including frame 2, which defines opening 3. In the drawing, windows 4 and 5 together register with and close opening 3. Window 4 is composed of sash 6 carrying glass panes 7 and 8. Window 5 is composed of sash 9 carrying glass panes 11 and 12. Plate 13 is mounted on frame 2, on a level with the upper end of sash 6, and to one side of opening 3. It is secured to the vertical surface of frame 2 by screws 14 or in any other suitable manner.

Plate 13 is integral with vertical cylinder 15 forming a bore which carries pin 17. One end of radial arm 18 is pivotally mounted on the lower end of pin 17. The other end of radial arm 18 is formed with upstanding stud 19 journalled in the bore defined by cylinder 22. Cylinder 22 is integral with plate 23 secured to the outer face of the top member 24 of sash 6 by screws 25 or in any other suitable manner. One end of radial arm 26 is pivotally mounted on the upper end of pin 17. The other end of radial arm 26 is formed with depending stud 27 journalled in the bore defined by cylinder 29. Cylinder 29 is integral with plate 30 secured to the back (as shown in Fig. 1) vertical surface of the top member 31 of sash 32 by screws 33 or in any suitable manner. Sash 32 carries the wire screenings 34 and 35 forming collectively with these, screen 36.

Referring to the upper right hand side of Fig. 1, plate 41 is mounted on frame 2 on a level with the upper end of sash 9 and to one side of opening 3. It is secured to the vertical surface of frame 2 by screws 42, or in any other suitable manner. Plate 41 is integral with vertical cylinder 43 forming a bore which carries pin 45. One end of radial arm 46 is pivotally mounted on the lower end of pin 45. The other end of radial arm 46 is formed with upstanding stud 47 journalled in the bore defined by cylinder 49. Cylinder 49 is integral with plate 50 secured to the outer face of the top member 51 of sash 9 by screws 52 or in any other suitable manner. One end of radial arm 53 is pivotally mounted on the upper end of pin 45. The other end of radial arm 53 is formed with depending stud 54 journalled in the bore defined by cylinder 56.

Cylinder 56 is integral with plate 57 secured to the back (as shown in Fig. 1) vertical surface of the top member 58 of sash 59. Sash 59 carries the screenings 60 and 61 forming collectively with these, the screen 62. The lower edge of the radial arms 26 and 53 must be mounted above and clear the top of sashes 6, 9, 32 and 59.

Referring to the lower right hand side of Fig. 1, plate 63 is mounted on frame 2, on a level with the lower end 62' of sash 9, and to one side of opening 3. It is secured to the vertical surface of frame 2 by screws 64 or in any other suitable manner. Plate 63 is integral with cylinder 65 forming the bore which carries pin 66. One end of radial arm 67 is pivotally mounted on the upper end of pin 66. The other end of radial arm 67 is formed with upstanding stud 68 journalled in the bore defined by cylinder 71. Cylinder 71 is integral with plate 72 secured to the outer face of the bottom member 62 of sash 9 by screws 73 or in any other suitable manner. One end of radial arm 74 is pivotally mounted on the lower end of pin 66. The other end of radial arm 74 is formed with upstanding stud 75 journalled in the bore defined by cylinder 77. Cylinder 77 is integral with plate 78 secured to the back (as shown in Fig. 1) vertical surface of the bottom member 79 of sash 59.

Referring to the lower left hand side of Fig. 1, plate 81 is mounted on frame 2, on a level with the lower end 82 of sash 6, and to one side of opening 3. It is secured to the vertical surface of frame 2 by screws 83 or in any other suitable manner. Plate 81 is integral with vertical cylinder 84 defining the bore which carries pin 86. One end of radial arm 87 is pivotally mounted on the upper end of pin 86. The other end of radial arm 87 is formed with upstanding stud 88 journalled in the bore defined by cylinder 91. Cylinder 91 is integral with plate 92 secured to the outer face of the bottom member 82 of sash 6 by screws or in any other suitable manner.

One end of radial arm 93 is pivotally mounted on the lower end of pin 86. The other end of radial arm 93 is formed with upstanding stud 94 journalled in the bore defined by cylinder 96. Cylinder 96 is integral with plate 97 secured to the back (as shown in Fig. 1) vertical sur face of the bottom member 98 of sash 32.

The upper edge of the radial arms 74 and 93 must be mounted below and clear the bottom of sashes 6, 9, 32 and 59.

Although the preferred arrangement is that shown in Fig. l, in which each co-acting pair of radial arms is mounted on a common axis, this is not absolutely essential, but the axes must in any case be close together.

The upper radial arms 26 and 35, must in any case, have a greater effective length than the radial arms 1t and 46 immediately below. The lower radial arms 74 and 93 must also have a greater effective length than the radial arms 67 and 87 immediately above.

It is further desirable to form the inside, i. e., the shorter radial arms, so short that they do not extend to the mid-point of the end members of the sash to which they are connected. It is likewise desirable to form the outer and longer radial arms so long that they extend past the mid-point of the end members of the sash to which they are connected. In any case, the difference between the effective lengths of the longer and the shorter radial arms must be such that the sash carried by the longer radial arms can be swung past the sash carried by the shorter.

The method of substituting one sash for another will be evident from the showing in Figs. 2,. 3 and 4. In Fig. 2 the sashes at the left hand side of Fig. 1 occupy the same relative positions in which they are shown in Fig. 1. The first step in exchanging the sashes is to move the sash 6 outwardly and turn it through an angle of approximately 180 to the position indicated for sash 6 and radial arm 18 in Fig. 3. Following this it is easily possible to reach past sash 6 and swing the radial arm 26 into the position indicated in Fig. 3, following which the sash 32 is turned through an angle ,of approximately 90 in the direction indicated by arrow 99. In this position the two sashes can be easily swung past one another and brought to rest in the final positions indicated in Fig. 4, in which sash 32 registers with and closes part of the opening 3 defined by the frame 2, while sash 6 rests back against the side wall of the building.

It is of course possible by making the top radial arms sufiiciently strong to hang the sashes from these and thereby obviate the necessity for the lower radial arms. This, however, involves a very heavy construction and the preferred arrangement is that shown in Fig. 1 in which there are radial arms at both top and bottom of each sash. While I have illustrated the invention in application to a combination of storm and screen windows, it will be self-evident that in those areas where the weather is not so inclement as to require double windows during the colder periods, the same construction may be used to make the regular window interchangeable with a screen.

I claim:

1. In combination with a window opening in a vertical wall, a sash containing glass or screening adapted to register with and close a part of said opening and a second sash containing screening or glass adapted to register with and close the same part of said opening, a first radial arm mounted on the face of said wall to one side of said opening for pivotal movement through a horizontal angle of about 180, a. pivotal connection between the upper end of said first sash and the outer end of said first rod permitting a turning movement of said sash in a horizontal plane, a second radial arm longer than said first radial arm mounted on the face of said wall, to one side of and above said opening, for pivotal movement through a horizontal angle of about 180, a
